- Borehole instability mechanism and Countermeasures Part-I
- Sidewall instability is including in borehole wall collapse, necking down, formation fracturing etc three basic types during the drilling or completion process. The first two causes may enlargement or reduction of borehole diameter, the last cause which could easily lead to lost circulation. Borehole instability is one of complex situations during the down hole drilling project, Seriously affect the address data of acceptance, drilling speed, quality and cost

- What’s the fluid solid control? How much do you know about it?
- It can be divided into two categories depends on its function, one kind is useful solid phase, such as bentonite, barite and other non - water soluble drilling chemical additives, and the other kind is some useless scraps, including well cuttings, poor quality soil and sand.

- How to Clarify Drilling fluids materials?
- Drilling fluids material can divide into clay type, weighting material and mud mixing water and oil etc.
Bentonite is the main material for water base drilling fluids. It can add viscosity and shearing ability, improve the stability of well hole.
Weighting material is grinding from inert substance which is insoluble in water. To deal with high pressure layer and stabilize the well wall, add weighting material can improve the density of drilling fluid. The most widely used in oilfield are Barite with API standard. Secondly used is Hematite and ilmenite, which is mainly used in acidulated

- How to settle down the drilling fluid contamination ? (part1)
- During well drilling. a variety of pollutants from the formation will into the drilling fluid, which make their performance not be suitable with the construction’s requirements, it’s known as drilling fluid invasion. Some pollutants seriously impact the drilling fluid rheology and filtration performance, or accelerate corrosion and damage to the drill rigs.
